Fractal Bézier

One rule of triangles applied over and over — a smooth Bézier curve or a Koch snowflake, depending on the rule. Change it and watch what grows.

Infraharmony

Harmony for rhythms: a grid of tones and rhythms on one scale, eight octaves apart. Play a chord in pitch and in time at once, or a canon at three speeds.

Anti-tag

Tag turned around: one runs, everyone chases, and whoever catches them runs next. A running game for adults and children together that balances itself.

Maze³

The classic maze with one more dimension: a see-through cube with a ball inside and no up or down. Turn it every way to find the exit — and the way through can tie itself in a knot.
